## Abstract A systematic permutation‐group approach for both the classification and description of the Feynman–Goldstone diagrams is presented. It allows us to “algebraize” the topological concepts and notions of many‐body diagrammatic techniques, for example, the connectivity and disconnectivity o
By symbolic summation methods based on difference fields we present a general strategy that transforms definite multi-sums, e.g., in terms of hypergeometric terms and harmonic sums, to indefinite nested sums and products. We succeeded in this task with all our concrete calculations of 2-loop and 3-l
